4 GB DDR4 desktop module

This 4 GB DDR4 module runs at 2133 MT/s and carries the PC4-17000 rating. It is built for standard desktop DIMM slots and suits basic office work, web browsing or light multitasking. The single-rank 1Rx8 layout keeps power draw modest. Buyers who need more than 4 GB of capacity should look elsewhere.

Motherboard slot and speed check

Confirm that the board accepts DDR4 DIMMs and can operate at 2133 MT/s or will down-clock a faster stick to that rate. Verify an open DIMM slot is available and that the platform supports unbuffered non-ECC memory. Systems limited to older DDR generations cannot use this module.

Module only, no extras

The package contains the memory stick alone with no heatsink, lighting or configuration software. Installation is a simple press into the slot; no drivers or utilities are required. The lack of bundled accessories keeps the focus on raw compatibility and cost.

Questions about this item

Does the SK hynix HMA451U6AFR8N-TF 4GB DDR4 module ship as a single stick or do I need to buy a second one for dual-channel?

The module is sold as a single 4GB DDR4 2133 stick; add a second identical stick if your board supports dual-channel.

I see PC4-2133P-UA1-10 and 1Rx8 on the label — which spec tells me the real-world bandwidth?

PC4-17000 is the peak transfer rate; the 1Rx8 organisation means eight chips on one rank for standard desktop compatibility.

Will the DDR4 2133 speed run at 2133 MT/s on my motherboard without changing BIOS settings?

The module defaults to JEDEC 2133 MT/s; most boards will boot at that speed automatically.
